FLUID-APPLYING MACHINE.

Application filed August 11, 1919.

To all whom t may concern.'

Be it known that I, Arms S. HAYDEN, a citizen of the United States, residing at Holbrook, in the county ot Norfolk and State of Massachusetts, have invented certain Improvements in Fluid-Applying Machines, ot which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several gures.

This invention relates to machines for applying fluids. The machine of the invention is particularly adapted for the application of blacking and other stains to the edges of the soles of slices, being herein shown in connection with the sole-blacking machine which is disclosed in a Patent No. 1,311,161, issued in the name of F. M. Furber, July 29, 1919. In sole-blacking apparatus of this type the coating fluid, in the form of a spray, is delivered upon the upper edge portion of a sole positioned horizontally by an edge-rest at one side, this being, in the present instance, the supply or suction conduit oi" the machine, and positioned vertically with respect to its distance from the spray nozzle by a gage, which also serves as a guard to protect from the spray the adjacent surface of the sole which is to remain uncoated.

An object of the invention is to provide for an alteration in the'width of the coated area. This I attain by means arranged to vary the position or the work transversely to thedirection or spray delivery, as by an edgerest adjustable in its relation to the source of spray and holding the work spaced therefrom. This rest I prefer to arrange about the supply conduit. It being shown as consisting orn an eccentric sleeve with means for fixing it in different positions. An organization of this character furnishes members contacting with the work at opposite sides of the spray-delivering means, one member being the edge-rest, and the other` the comhined gage and guard, which members are relatively adjustable transversely of the spray.

In fluid-applying machines employing a spray, the extension into the path of said spray of elements of the machine tends to divert it from the propel' course or to gather it into drops which will be thrown into the Speccation of Letters Patent.

air to be wasted and possibly cause injury to surrounding objects or to the operator by their inhalation. To prevent the position-varying means from producing such effects is another object of the invention, and to this end I locate the means for fixing the position-varying means out of the path of the spray. lVith the rest carried upon the supply conduit, the position-determining means therefor may be adjacent to the applying device. Since, when a spray nozzle is employed, a point thus located will be near the narrower portion oi the jet before it spreads laterally in its passage toward the work, the position-determining means may readily be kept clear of the iluid.

In the accompanying drawing, illustrating one form of my invention,

Figure 1 is a side elevation of a portion 01"' a sole-blacking machine embodying my invention, parts being in section; and

Fig. 2 is a perspective view illustrating the work in contact with the positioning means, and including a portion of the nozzle. l

The numeral 10 designates a portion of the supporting frame of a sole-blacking machine, this frame carrying a hollow arm 12, to which is connected a source of air pressure. The air is delivered from the arm to an outlet tube 141 of an atomizing or spray-producing device carried by a head 16 mounted upon the outer extremity of the arm. The head has delivering to it a supply or suction pipe or conduit 1S rising from a Huid receptacle 2O supported upon the frame, and having at its lower end the usual strainer 22. The opening at the'upper extremity of the conduit 18 delivers to a' horizontal mixing passage 24, into which the outlet tube 14: projects. In the under side of the head, in alinement with the nozzle 14, is a delivery opening 26. This sprayproducing device operates in the usual manner of atomizers, the air blast issuing through the opening of the nozzle 14 and passing through the delivery opening 26, producing a suction through the conduit 18 which raises the coating fluid from the receptacle into the mixing chamber, from which it is carried by the air blast as a spray through the delivery opening 26.

Secured to the outer side of the head 16 by a screw 28 is a gage-plate 30, the lower of the work, and is so related to the opening 26 that it protects the inner area of the sole operated upon from the spray, thus preventing waste of the coating fluid.

Opposite the gage 30, about the conduit 18, is a sleeve 32, shown as ttingit to turn thereon, but beingI at its exterior eccentric to the surface of said conduit. The amount of this eccentricity should be substantially equal to the variation which it is desired to produce in the width of the coated area of the sole. The sleeve may be fired in position by a screw 34 threaded through its wall, preferably at the thickerside, to give proper engagement for the screw threads, and at or near the upper extremity of the sleeve. The length of the screw may be such that its head is substantially flush with the exterior of the sleeve. Thus located, it is entirely clear of the path of the spray, regardless of the angle through which the sleeve is turned, since it is adjacent to the point at which the jet issues from the delivery opening 26 in its most contracted form. If the screw or position-determining device were situated near the bottom ot the sleeve, or projected much beyond its surface when turned toward the gage 30, it might be struck by the spray, causing this to spetter and waste. It might also interfere with the application of the work to the rest. With my arrangement there is presented to the spray and the work only the smooth, unbroken exterior of the adjusting sleeve. It will be obvious, that by loosening the screw 34 and turning the sleeve about the conduit, the surface which by its contact with the sole edge determines the position transversely of the path of the spray, will be changed, so that the band of coating produced may, within the limits of the thickness of the sleeve wall, be of any desired width.v

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1.
